About Jacksepticeye

Irish Let's Play YouTuber with 31.2M subs; latest upload Sep 12, 2026 (Moldrise playthrough).

Seán McLoughlin didn’t set out to become Ireland’s most-subscribed YouTuber — he set out to have fun playing games, loudly, and let the internet watch. It worked beyond anyone’s imagining. The jacksepticeye channel has been a daily fixture of gaming culture for more than a decade: horror scream sessions, indie deep cuts, and AAA adventures, all delivered with the “top of the mornin’ to ya” warmth that made him a global comfort watch. The green hair, the catchphrases, the relentless upload schedule — it all added up to one of YouTube’s most durable careers.

What kept the audience loyal through every era of the algorithm was the person underneath the energy. Seán’s candor about depression and burnout, his public grief after losing his father in 2021, and the millions raised through his annual Thankmas charity events turned a Let’s Play channel into something closer to a community institution. Add the business empire — CLOAK with Markiplier, Top of the Mornin’ Coffee — and you get the blueprint for creator longevity: be undeniable on camera, be real off it, and never stop showing up.

About this creator

Words by Julian Cole

Jacksepticeye — Seán McLoughlin — is Ireland’s YouTube king: the high-energy Let’s Player whose “top of the mornin’ to ya” became the most cheerful greeting on the internet. The most-subscribed YouTuber in Ireland, and one of the platform’s defining voices. From horror-game scream sessions to charity streams that raised millions, from the CLOAK clothing empire to Top of the Mornin’ coffee, Seán built a career on an unbeatable formula: relentless positivity, genuine heart, and an upload schedule that never quit. A decade-plus at the top, through every YouTube era — the algorithm changed; Seán did not.

Born Seán William McLoughlin on February 7, 1990, and raised in Athlone, County Westmeath, Ireland, Seán started the jacksepticeye channel in December 2012, uploading Let’s Play videos under a name borrowed from a football nickname — “Jack” plus “septiceye,” earned after an eye injury. The early years were slow: by mid-2013 he had around 2,500 subscribers. Then came the break that changed everything: PewDiePie’s 2013 subscriber shout-out contest. Seán won, gaining 15,000 subscribers practically overnight — and unlike most contest winners, he kept every one of them and multiplied them by the thousand.

The formula was deceptively simple: play horror games, indie gems, and AAA adventures with the infectious enthusiasm of someone who genuinely cannot wait to show you what happens next. Five Nights at Freddy’s, Happy Wheels, and his legendary Undertale playthrough turned gameplay into theater. The catchphrase — “Top of the mornin’ to ya, laddies!” — became one of YouTube’s most recognizable intros. The milestones stacked up: 10 million subscribers in 2016, 20 million in 2020, and past 30 million in 2024, making him the most-subscribed YouTuber in Ireland by a distance.

As the channel grew, the business empire grew alongside it. In 2018 he co-founded CLOAK, the gaming lifestyle clothing brand, with Markiplier — creator merch elevated to actual fashion. In 2020 he launched Top of the Mornin’ Coffee, his own coffee company, built on the running joke that fueled a thousand morning uploads. Both succeeded because the trust was real: Seán’s audience buys in because he’s never sold them out.

What the community cherishes most is the heart. In 2018 he posted a raw, honest video about his struggles with depression and burnout — at the time, one of the most vulnerable things a creator of his size had ever shared. When his father passed away in January 2021, he stepped back from uploading to grieve, and the outpouring of support showed how deeply the audience loved the man behind the energy. Millions of young viewers learned it was okay to struggle — from their favorite loud Irish gamer.

The charity work is the legacy. Thankmas, his annual December charity event launched in 2020, has raised millions of dollars for organizations like World Central Kitchen and Crisis Text Line, with the community smashing fundraising records year after year. It’s the purest expression of what the channel has always been: joy, weaponized for good.

Seán’s influence extends past the platform: a cameo as himself in the 2021 film Free Guy, collaborations with the biggest names in gaming, and the 2022 “How Did We Get Here?” tour that brought the energy to live stages across the UK and Europe. Through it all, the upload schedule became legend — years of near-daily videos without the quality ever dipping.

Off camera, Seán married fellow creator Gab Smolders, and the couple’s shared creative life has become a quiet cornerstone of the channel’s second decade. He’s been open about therapy, about slowing down, about the difference between performing happiness and feeling it — and the audience has only loved him more for the honesty.

From Athlone to the world, Jacksepticeye remains gaming YouTube’s most reliable smile: loud, kind, and utterly indefatigable. The Irish ambassador era is the deeper story — a voice for a whole country’s internet, carrying cultural weight far beyond gaming. The accent is famous; the pride is real. Top of the mornin’ — forever.
